The place information 52 is information that does not include a proper noun and can specify the transmission place 41 by combining with the communication range 40. Further, the purpose information 51 does not include a proper noun.
Specifically, it is as follows.

First, the user 20 starts an application program that realizes the function of the message communication device 100.
In step S101, the message generation unit 110 displays the generation screen of the broadcast message 21 on the display device 941.
In step S102, the message generation unit 110 acquires the target information 51 and the location information 52 from the user 20 via the generation screen. The message generation unit 110 sets the target information 51 and the location information 52 in the broadcast message 21.
Specifically, it is as follows.

For example, the message generation unit 110 displays the target list 151 on the generation screen. The message generation unit 110 causes the user 20 to select the desired target information 51 from the target list 151. The message generation unit 110 may allow the user 20 to select the desired target information 51 from the target list 151 on the generation screen by a pull-down method.
Further, the message generation unit 110 displays a list of locations 152 on the generation screen. The message generation unit 110 causes the user 20 to select the desired location information 52 from the location list 152. The message generation unit 110 may allow the user 20 to select the desired location information 52 from the location list 152 on the generation screen by a pull-down method.

FIG. 4 is a diagram showing an example of a list 151 of the objects according to the present embodiment.
The target list 151 is preset by the user 20. The purpose of the broadcast message 21 is set in the purpose list 151. In FIG. 4, purpose information 51 such as a request for help, a recruitment of taxi carpools, and a notification that a train seat will be vacant is set.
The user 20 who uses the voice service of the message communication system 500 downloads an application program that realizes the function of the message communication device 100. Then, the user 20 performs initial registration of the application program that realizes the function of the message communication device 100.

If the other is selected by the user 20, the message generation unit 110 may have the user 20 directly input the purpose. Alternatively, the message generation unit 110 may have the user 20 input the details of the target information 51. At this time, the message generation unit 110 displays a warning on the display device 941 to alert the user 20 not to input a proper noun to the target information 51.

FIG. 5 is a diagram showing an example of a list 152 of places according to the present embodiment.
The list of places 152 is preset by the user 20. In the place list 152, the place information 52 preset by the user 20 is set. The location information 52 is information for specifying a transmission location 41 to be transmitted to another message communication device. In FIG. 5, location information 52 such as the ticket gate of "X" at a station, a taxi stand, and the vicinity of the "X" th door of both "X" eyes of a train is set.
The place information 52 does not include a proper noun. Further, the location information 52 is information that can specify the transmission location 41 by combining with the communication range 40. That is, the place list 152 does not include the proper noun, and the place information 52 that can specify the transmission place 41 by combining with the communication range 40 is set.

For example, when the user 20 wants to use the voice-calling service of the message communication system 500 to recruit taxi carpools, he / she calls out to other users in the vicinity of the taxi stand. At this time, the taxi stand where the user 20 is located becomes the transmission place 41. Therefore, the user 20 selects the "taxi stand" as the location information 52. The location information 52 does not include specific proper nouns such as Tokyo Station or Osaka Station. However, since the broadcast message 21 reaches only the communication range 40 having a radius of about 100 m, other users who have received the broadcast message 21 can specify the taxi stand as the transmission place 41.

Further, when the user 20 wants to use the voice-calling service of the message communication system 500 to request assistance at the station, he / she calls out to other users in the vicinity of the station. At this time, the ticket gate of the station where the user 20 is located becomes the transmission place 41. Therefore, the user 20 selects "the ticket gate of" X "at the station" as the location information 52. When "the ticket gate of" X "at the station" is selected, the message generation unit 110 causes the user 20 to input information for specifying the ticket gate in the "X" part. For example, the message generation unit 110 causes the user 20 to input information for specifying a ticket gate such as a south exit or a north exit in the “X” portion. At this time, the place information 52 does not include a specific proper noun such as Tokyo station or Osaka station. However, since the broadcast message 21 reaches only the communication range 40 having a radius of about 100 m, other users who receive the broadcast message 21 can specify the ticket gate at the north exit of the surrounding station as the transmission place 41. ..

In addition, other columns may be provided in the list of places 152. When other items are selected by the user 20, the message generation unit 110 may have the user 20 directly input the location information 52. Alternatively, the message generation unit 110 may have the user 20 input the details of the location information 52. At this time, the message generation unit 110 displays a warning on the display device 941 to alert the user 20 not to input a proper noun to the location information 52.

Next, in step S103, the message generation unit 110 acquires the source information 53 from the user 20 via the generation screen. The message generation unit 110 sets the source information 53 in the broadcast message 21. The source information 53 is information that identifies the user 20 who carries the source message communication device 100. The source information 53 is information that does not include a proper noun and can identify the user 20 by being combined with the communication range 40. The message generation unit 110 generates the broadcast message 21 including the source information 53.

For example, the message generation unit 110 displays a list of senders 153 on the generation screen. The message generation unit 110 causes the user 20 to select the desired source information 53 from the source list 153. The message generation unit 110 may allow the user 20 to select the desired source information 53 from the source list 153 on the generation screen by a pull-down method.

FIG. 6 is a diagram showing an example of a list of senders 153 according to the present embodiment.
The source list 153 is preset by the user 20. In the sender list 153, the sender information 53 preset by the user 20 is set. The source information 53 is information for identifying the user 20 who wants to transmit to another message communication device. In FIG. 6, source information 53 such as a man with an “X” tie and a brown business bag and a man with a smartphone with an “X” color cover is set.
The source information 53 does not include a proper noun. Further, the source information 53 is information that can identify the user 20 by combining with the communication range 40. That is, the source information 53 that does not include the proper noun and can identify the user 20 by combining with the communication range 40 is set in the source list 153.

For example, when the user 20 wants to use the voice service of the message communication system 500 to recruit taxi carpools, he / she calls other users around the taxi stand. At this time, the user 20 needs to have another user who applied for the taxi carpool recruitment identify himself / herself. Therefore, the user 20 selects "a man who has a smartphone with an" X "cover" as the source information 53. When "a man holding a smartphone with an" X "cover" is selected, the message generation unit 110 causes the user 20 to input information for specifying a color or a pattern in the "X" portion. For example, the message generation unit 110 causes the user 20 to input information for identifying the cover of the smartphone, such as a black stripe, in the “X” portion. At this time, the source information 53 does not include a specific proper noun such as a name. However, since the broadcast message 21 reaches only the communication range 40 having a radius of about 100 m, another user who receives the broadcast message 21 can see "a smartphone with a black stripe cover" at the taxi stand, which is the transmission location 41. It is possible to identify "a man who possesses a".

Further, other columns may be provided in the list of senders 153. When other items are selected by the user 20, the message generation unit 110 may have the user 20 directly input the source information 53. Alternatively, the message generation unit 110 may have the user 20 input the details of the source information 53. At this time, the message generation unit 110 displays a warning on the display device 941 to alert the user 20 not to input a proper noun to the source information 53.

Further, when the message generation unit 110 causes the user 20 to select the target information 51, the location information 52, and the source information 53, the message generation unit 110 includes a proper noun in any of the target information 51, the location information 52, and the source information 53. You may display a warning so that there is no such thing. Alternatively, the message generation unit 110 warns that when the user 20 finally confirms the broadcast message 21, the target information 51, the location information 52, and the source information 53 do not include a proper noun. It may be displayed.

In step S104, the message transmission unit 120 broadcasts the broadcast message 21 to another message communication device by short-range wireless communication. The message transmission unit 120 realizes a communication protocol based on broadcast communication in a communication area useful for a person to act on foot via a communication device 950. Specifically, the message transmission unit 120 realizes a communication protocol based on broadcast communication in a Wi-fi (registered trademark) communication area or a Bluetooth (registered trademark) 4.0 or higher communication area. More specifically, the message transmission unit 120 realizes broadcasting by short-range wireless communication by using a BLE broadcast communication method called iBeacon (registered trademark).

FIG. 7 is a flow chart of processing when the broadcast message 22 according to the present embodiment is received.

In step S201, the message receiving unit 130 receives the broadcast message 22 from another message communication device and stores it in the storage unit 150. Specifically, the message receiving unit 130 receives the broadcast message 22 broadcast from another message communication device via the communication device 950 and stores it in the storage unit 150.

The message display unit 140 displays the broadcast message 22 on the display device 941 when the purpose represented by the target information 51 included in the broadcast message 22 is included in the target list 151.
Specifically, it is as follows.

In step S202, the message display unit 140 determines whether the target information 51 included in the broadcast message 22 is included in the target list 151 of the storage unit 150. That is, the message display unit 140 matches the target information 51 of the broadcast message 22 with each of the target list 151. Specifically, the message display unit 140 digitizes the target information 51 included in the broadcast message 22. Then, it is assumed that each purpose information included in the target list 151 is also quantified in advance. Then, the message display unit 140 matches the target information 51 based on the degree of coincidence between the numerical value of the target information 51 included in the broadcast message 22 and the numerical value of each target information included in the target list 151.
If it is determined that the target information 51 matches, the process proceeds to step S203. If it is determined that the target information 51 does not match, the process proceeds to step S204.
In step S203, the message display unit 140 displays the broadcast message 22 on the display device 941 of the message communication device 100 via the output interface 940.

FIG. 8 is a display example of the broadcast message 22 according to the present embodiment.
When the target information 51 included in the broadcast message 22 received from another message communication device matches any of the target information in the list 151 of the purpose of the own device, the message display unit 140 displays the broadcast message 22 in the display device 941. Display on.
In FIG. 8, "Please help me" is displayed as the purpose information 51. In addition, as the location information 52, "This is the ticket gate at the south exit of the station" is displayed. In addition, as the source information 53, "a man with a smartphone with a yellow cover" is displayed.
As described above, the broadcast message 22 does not include any proper noun. However, the user 20 who sees the broadcast message 22 can identify the man holding the smartphone with the yellow cover at the ticket gate of the south exit of the surrounding station as the sender. Then, the user 20 can offer caregiving to the sender user.

In step S204, when the display threshold time 154 has elapsed after displaying the broadcast message 22 on the display device 941, the message display unit 140 stops the display and erases the broadcast message 22 from the storage unit 150.

*** Other configurations ***
<Modification 1>

In FIG. 9, the confidence point 155 is accumulated in the storage unit 150.

The message transmission unit 120 transmits a trust point 155 indicating trust from the user who is the source of the broadcast message 21 to the user who carries another message communication device. For example, when the user sends the broadcast message 21 for the purpose of assistance, the user can send the trust point 155 to another user who kindly assists.

Further, the message communication device 100 has a mechanism for preventing unauthorized acquisition of the trust point 155.
The user registers the message communication device 100 with a certification body that certifies the message communication device in advance. Then, the message transmission unit 120 transmits the trust point 155 to the message communication device of another user together with the information indicating the success of the authentication by the authentication body.
In this way, when each user registers the terminal with the certification body in advance and gives points to the person who does not know the name, the certification body certifies it. For example, the message transmission unit 120 transmits the trust point 155 together with the certificate from the authentication authority to the message communication device of another user to prevent falsification by the certificate.

Further, the message communication device of the user who receives the trust point 155 performs the following processing.
The message receiving unit 130 receives the trust point 155 from the other message communication device 100 and stores it in the storage unit 150. The message display unit 140 adds and displays the trust point 155 stored in the storage unit 150 to the broadcast message 22.

FIG. 10 is a display example of the broadcast message 22, that is, the voice message according to the first modification of the present embodiment.
As shown in FIG. 10, the trust point 155 received from another user may be added to the voice message and displayed.
At this time, in the message communication device 100, the trust points 155 received from other users are accumulated without being erased. Then, at the time of transmitting the voiced message and at the time of responding to the voiced message, the trust point 155 is added and transmitted. Then, the trust point 155 is added to the voice message and displayed. This function can be expected to improve the creditworthiness of people. In addition, the user can speak with confidence and respond to the voice.
